PROBLEM TO BE SOLVED: To provide an indoor surface structure disposed at the surface surrounding a room, which includes a heat insulator of resin foam, with an excellent function for shielding radiant heat from the outside, hardly causing the problem of dew condensation on the indoor side, and making a strong joint to the surface material to be sprayed with a resin foam precursor; and a method for manufacturing the same.SOLUTION: A single side corrugated board includes a corrugated portion having a corrugated shape and a flat plate portion, which are laminated. A nonwoven fabric having a metal deposition layer is laminated to the flat plate portion side of the corrugated board, with the metal deposition layer facing outside, so as to form a heat shielding sheet. On the corrugated portion side of the heat shielding sheet, a resin foam layer is laminated on the entire surface of the corrugated portion in a close contact state. An indoor surface structure includes a heat shielding laminate composed of the heat shielding sheet and the resin foam layer, being disposed at the surface surrounding a room selected from a ceiling surface, a wall surface, and a floor surface, with the metal deposition layer facing the outside of the room. A method for manufacturing the indoor surface structure includes: laminating the heat shielding sheet to a frame body such that the indoor space side is partitioned from the opposite side, with the corrugated portion of the heat shielding sheet facing the inside; spraying the precursor of the resin foam to the heat shielding sheet so that the space surrounded by the inner side of the frame body is filled with the resin foam to be cured; and then combining the board with the frame body. |
